The delta of an option is the mathematical parameter that measures how much the price of an option changes with price changes in the underlying asset.

For instance, an option with 0.5 delta would gain $0.50 in value with every $1 gain in price of the underlying asset. It will also drop by $0.50 in value with every $1 drop in price of the underlying asset.

Take note that delta is also changing all the time due to Gamma so it should be taken more as a research reference rather than an absolute prediction of options prices.

How do you use delta in option trade?

Delta is the measurement of the sensitivity of the price of an option to the price movement of the underlying stock.Delta can be useful in predicting profits, having a feel of the probability of the option ending up in the money by expiration under normal conditions and for hedging.In predicting profits, an option with 0.5 delta would move $0.50 when the underlying stock moves $1. By summing up the delta of your options, you would know how much profit you would make with a predicted move on the underlying stock. For instance, if the underlying stock is expected to move by $5, an option with 0.5 delta would move $2.50.Delta is also a measure of the probability that an option would end up in the money by expiration. An at the money option has 0.5 delta has a 50% chance of ending up in the money. The deeper in the money the option goes, the bigger the delta and hence the higher the chance it will end up in the money. Options with delta of 1 would almost definitely end up in the money by expiration under normal conditions.Delta is perhaps most important for hedging in the area of delta neutral hedging.

What is the gamma of an option?

The rate of change for delta with respect to the underlying asset's price.

When the option being measured is deep in or out of the money, gamma is small. When the option is near the money, gamma is largest.
